A methodology for energy multivariate time series forecasting in smart buildings based on feature selection
(Elsevier, 2019-05-10) González Vidal, Aurora; Jiménez Barrionuevo, Fernando; Skarmeta Gómez, Antonio; Ingeniería de la Información y las Comunicaciones; Facultades de la UMU::Facultad de Informática
The massive collection of data via emerging technologies like the Internet of Things (IoT) requires ﬁnding optimal ways to reduce the created features that have a potential impact on the information that can be extracted through the machine learning process. The mining of knowledge related to a concept is done on the basis of the features of data. The process of ﬁnding the best combination of features is called feature selection. In this paper we deal with multivariate time-dependent series of data points for energy forecasting in smart buildings. We propose a methodology to transform the time-dependent database into a structure that standard machine learning algorithms can process, and then, apply different types of feature selection methods for regression tasks. We used Weka for the tasks of database transformation, feature selection, regression, statistical test and forecasting. The proposed methodology improves MAE by 59.97% and RMSE by 40.75%, evaluated on training data, and it improves MAE by 42.28% and RMSE by 36.62%, evaluated on test data, on average for 1-step-ahead, 2-step-ahead and 3-step-ahead when compared to not applying any feature selection methodology.

A Transfer Learning Framework for predictive energy-related scenarios in Smart Buildings
(IEEE Transactions on Industry Applications, 2023-02-01) González Vidal, Aurora; Niu, Shuteng; Song, Houbing; Skarmeta Gómez, Antonio; Mendoza Bernal, José; Ingeniería de la Información y las Comunicaciones; Facultades de la UMU::Facultad de Informática
Human activities and city routines follow patterns. Transfer learning can help achieve scalable solutions towards the realisation of smart cities accounting for similarities between regions, domains, and activities. In this study, we propose a Transfer Learning-based framework for smart buildings to test this hypothesis in energy-related problems. Our framework has two major components: the network creation and the transferable predictive model. In order to create the network that groups buildings sharing characteristics, we evaluated two strategies: a novel clustering algorithm for mixed data, k-prod, and clustering the image-based representation of time series. Then, a combination of Long Short Term Memory and Convolutional Neural Network was trained on the centroids of the clusters for energy consumption prediction. The Coefficient of Variation of the Root Mean Squared Error (CVRMSE) of the predictions in such clusters vary between 3.85 and 58.85 %. The obtained parameters were transferred to the rest of the buildings for predictive purposes, finding accurate results in buildings with little data. Our framework deals with insufficient training data since parameters from scenarios with more sensors can be received. It also carries out state-of-the-art performance on 3 datasets from different sources having in total 533 rooms/buildings and two energy efficiency domains: consumption prediction reducing the CVRMSE in a 21.6 %, and air conditioning usage prediction moving from a 4.18 % to a 0.28% CVRMSE. Our framework extracts more knowledge from available IoT deployments, so that smartness could be spread between environments at a fewer cost given that less individual effort will be needed.

An application of structural equation modeling with partial least squares to analyze life satisfaction by degrees of urbanization.
(AIMS Press, 2024-08-05) Sánchez-Martí, José A.; Esteban Yago, Miguel; Economía Aplicada
The objective conditions of people’s lives have historically played a greater role than subjective perceptions. However, this trend is shifting, accompanied by an ongoing debate about life satisfaction and urbanization. This research has two objectives, the first is to test the hypothesis of the urban paradox. The second is to analyze the differences in the determinants of life satisfaction by urbanization levels. In order to determine the degrees of urbanization, a geographic grid was used to distinguish between rural, intermediate, and urban areas. In addition, a multi-group analysis in structural equation models with partial least squares was conducted to analyze the determinants of life satisfaction. The model has been developed using three general determinants: economic situation, health, and social relations, which has been applied to a case study of the Region of Murcia. The database used for this study includes 2462 samples. The population living in rural areas showed less life satisfaction. Regarding the determinants, it was found that health acts as a partial mediator of social relations. Differences were also observed in the intensity of the determinants according to the degree of urbanization. Thus, the degree of urbanization acts as a moderator of life satisfaction. This research is noteworthy because it provides valuable insights for guiding regional public policies.

An open IoT platform for the management and analysis of energy data
(Elsevier, 2019-03-01) Fernando Terroso-Sáenz; González Vidal, Aurora; Ramallo González, Alfonso Pablo; Skarmeta Gómez, Antonio; Ingeniería de la Información y las Comunicaciones; Facultades de la UMU::Facultad de Informática
Buildings are key players when looking at end-use energy demand. It is for this reason that during the last few years, the Internet of Things (IoT) has been considered as a tool that could bring great opportunities for energy reduction via the accurate monitoring and control of a large variety of energy-related agents in buildings. However, there is a lack of IoT platforms specifically oriented towards the proper processing, management and analysis of such large and diverse data. In this context, we put forward in this paper the IoT Energy Platform (IoTEP) which attempts to provide the first holistic solution for the management of IoT energy data. The platform we show here (that has been based on FIWARE) is suitable to include several functionalities and features that are key when dealing with energy quality insurance and support for data analytics. As part of this work, we have tested the platform IoTEP with a real use case that includes data and information from three buildings totalizing hundreds of sensors. The platform has exceed expectations proving robust, plastic and versatile for the application at hand.

Applicability of Big Data Techniques to Smart Cities Deployments
(0001-09-16) M. Victoria Moreno; Fernando Terroso-Sáenz; González Vidal, Aurora; Valdés Vela, Mercedes; Skarmeta Gómez, Antonio; Zamora Izquierdo, Miguel Ángel; Victor Chang; Ingeniería de la Información y las Comunicaciones; Facultades de la UMU::Facultad de Informática
This paper presents the main foundations of big data applied to smart cities. A general Internet of Things based architecture is proposed to be applied to different smart cities applications. We describe two scenarios of big data analysis. One of them illustrates some services implemented in the smart campus of the University of Murcia. The second one is focused on a tram service scenario, where thousands of transit-card transactions should be processed. Results obtained from both scenarios show the potential of the applicability of this kind of techniques to provide profitable services of smart cities, such as the management of the energy consumption and comfort in smart buildings, and the detection of travel profiles in smart transport.

Arte contra la desigualdad: intervención socioeducativa a través de la fotografía en centros de educación primaria
(Universitad Jaume I, 2023-04-01) López Ruiz, David; Escarvajal López, Eva; Expresión Plástica, Musical y Dinámica; Facultades de la UMU::Facultad de Educación
Some educational scenarios show a marginal reality that is not always perceived. Photography constitutes an ad hoc method to capture both the investigative process and the experiences and points of view of the students, allowing to know the reality of students in vulnerable situations, the promotion of interculturality and the detection of conditions or circumstances that influence the perpetuation of social exclusion, in order to improve the starting situation. To intervene in this situation, a qualitative research was carried out with a total of 118 students from the third cycle of the Primary Education stage. A series of exercises based on photography were carried out as the main tool for creation and expression. The project was focused from visual research based on the Arts, using photographs as a means of exhibition and transmission of information, being able to capture the main data of the process and the results through images. This proposal served as a pretext to trigger new actions and socio-educational implications that not only directly influenced the students, but also went beyond the school walls.

Caminhar como uma prática de conhecimento sensível: a relevância ecológica do flâneur e a deriva na Educação Ambiental
(Universidade Federal do Rio Grande (FURG), 2025-11-10) Ruiz Bañón, María Luz; Bellas Artes
Este artigo propõe uma abordagem metodológica de educação ambiental, baseada em epistemologias ecológicas, que articula uma experiência educativa de caminhada pedagógica, registro sensorial e mapeamento afetivo como estratégias de reapropriação do território. Em diálogo com a fenomenologia, os estudos sensoriais e a antropologia da caminhada, ele recupera a figura do flâneur e a deriva para explorar o corpo em movimento como uma forma de sentir-pensar o ambiente mais do que humano. Essas práticas corporais e multissensoriais favorecem uma percepção incorporada e relacional do ambiente, promovendo uma ética de atenção, cuidado e reciprocidade com os seres vivos. É evidente que tais metodologias geram conhecimento situado e contra-hegemônico que desestabiliza o antropocentrismo, contribuindo para uma educação ambiental crítica e aberta ao medo, com o potencial de inspirar novas formas de aprendizagem coletiva e práticas pedagógicas transformadoras orientadas para a justiça ecológica. ---------------------------

Economic valuation of allotment gardens in peri-urban degraded agroecosystems: the role of citizens’ preferences in spatial planning
(Elsevier, 2021-02-15) Albaladejo García, José Antonio; Alcon, Francisco; Martínez Paz, José Miguel; Economía Aplicada; Facultad de Economía y Empresa
Allotment gardens (AGs), one of the basic types of urban gardening, provide goods and services to the urban population beyond food supply. Therefore, the efficient planning and management of AGs must take into account both the social welfare provided by the ecosystem services (ES) associated with these spaces and spatial considerations. The distance of the AGs from the citizens, their accessibility and the presence of substitutes are aspects that have not been studied extensively in the scientific literature. In this context, this paper evaluates the creation of AGs in a peri-urban degraded agroecosystem in Murcia (SE-Spain). To this end, the values of ES are quantified economically, as are the influences of the socio-economic and spatial characteristics. A survey was undertaken on a representative sample of households in Murcia city, from which the willingness to pay (WTP) for owning an AG and the factors influencing the valuation were determined. The results indicate that provisioning services are the ES valued most highly, followed by regulating and cultural ES. The valuation of the project for the whole population is 5.4 €/household/month, with a WTP of 17.2 €/household/month for owning an AG plot. Multivariate analysis showed the importance of ES and spatial factors in this valuation. This WTP spatial study shows the existence of local patterns to be considered in the evaluation of new AGs location alternatives. These results will be useful to urban planners in their decision making.

European Union policies and their role in combating climate change over the years
(Springer, 2022-01-08) Cifuentes Faura, Javier; Ciencia Política, Antropología Social y Hacienda Pública; Facultad de Economía y Empresa
The worrying environmental situation and increased public awareness in recent years have led many countries to take measures to reduce negative impacts on the environment. The European Union (EU) has been one of the most active in environmental protection with the formulation of policies aimed at preserving the health and well-being of citizens and protecting natural resources. One of the objectives of environmental policies is to make the economy of its member states more environmentally friendly, although this requires finding solutions to major challenges such as climate change, the scarcity of natural resources, the emission of polluting gases, and unsustainable consumption and production. This article reviews the main policies that have been implemented in the EU to reduce environmental problems and the scope of climate change conferences. It offers solutions to promote sustainability that could be adopted by companies, individuals, and governmental institutions to jointly contribute to achieving a more sustainable world, where problems such as climate change or the emission of polluting gases are minimized. The aim is to follow the principles of the Circular Economy and the European Green Deal.
